Just got the update....downloaded and installed just fine. Things I have noticed.....phone feels a little faster....opening apps like camera, phone, texts all seem faster. Also, the shutter speed in the stock camera app has gotten a little faster. The only other thing in the camera app that I noticed was the icon in the top left corner to switch between rear and front cameras is a slightly different icon. Other than those things I mentioned , everything else seems the same

Remember that ROM updates typically wipe both the app cache and the Dalvik cache, which will make any phone faster for a few days.

It is not possible: update broke root and locked bootloader tight. There is no solution.
If you have a Developer edition phone, the update does not touch the bootloader and one can install a custom recovery via Odin and then install a pre rooted rom.
AGAIN: NO SOLUTION OTHERWISE.
